Lets step by step. I've just left the TD and the a/c is in DES, NAV modes.
So I ask to PNF to activate appr phase. That will force me to select speed.
I should remenber that the speed in MACH mode.
The first load for me.
The second problem I encounter is speed constrain monitoring and executing
by my self!
Continue: when THR IDLE appeared on FMA the FMGS ask me
about more drug or I may increase speed to maintaine vertical profile. That leads
to excessive speed carrying that requires additional distance to be then vanished.
The third proublem is calculation of additional distancefor that.
The EXP DES mode are no longer available.
As I mentioned the prediction accuracy of descent (the blue hook on PFD)
is acceptable to peform approach. The FMGS takes into account all
altitude constrains. I think that's it. CON RESPECTO
